SINGLETREE.

SPECIFICATION forming part of Letters Patent No. 424,873, dated April 1,1890.

Application filed December 9, 1889. Serial No. 333,075. (No model.)

T0 all whom t may concern:

\ Be it known that I, PETER FISHER, a citizen of the UnitedStates, and aresident of Pomeroy, in the county of Meigs and State of Ohio, haveinvented certain new and useful Improvements in Singletrees and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in 'theart to which it appertains to make and use the s ame.

My invention relates to improvements in singletrees for Wagons and othervehicles; and its object is to provide a singletree having a springcombined therewith in such manner that the same shall have a slightyielding movement wlien the horse starts, thereby rendering theoperation of starting the vehicle easier and making the strain upon theanimal more uniform.

The invention consists in the combination, with a singletreehorizontally movable, of a clip secured to the cross-bar of the shaftsand carrying at its free end a-leaf-spring the ends Vof whichbearagainst the said singletree, as

hereinafter more fully described.

The invention also consistsin certain other novel features ofconstruction and new combination of parts, hereinafter fully described,

and definitely pointed out in the appended claim. l

In the accompanying drawings, Figure l is a plan view of a singletreeconstructed according to my invention. Fig. 2 is a front View of thesame.

In the said drawings, the reference-n umeral l designates an ordinarysingletree having at the ends the clips 2, to which the usual tracehooks3 are secured.

The numeral 4 designates the central clip, which is secured to thecross-bar of the shafts in the ordinary manner. This clip consists of aplate or band of metal bent over upon itself, so as to embrace thesingletree, as seen in Fig. 2. y

The singletree is provided on its upper and lower sides with lugs orways 5, which serve as guides for the clip and prevent any lateralmovement thereof on the tree. The ends of the clip are connected bymeans of a bolt 6, passing therethrough and also through the outer leafof the spring hereinafter described. This bolt is headed at one end andscrew.- threaded at the other to receive a correspondingly-threadedbinding-nut 7.

The numeral 8 designates an ordinary leafspring composed of any numberof leaves desired, united together at or near their centers by bolts orrivets. The ends of the inner leaf of the spring are embraced by andwork in flanged lugs 9, near the ends of the singletree. The outer leafof the spring is provided with a curved bosslO, perforated to allow thebolt 6 to pass therethrough and secure the spring to the clip. At itsrear end, or where the clip is secured to the shafts, it is providedwith a bar ll, which limits the backward movement of the singletree.

From the above it-will be seen that I provide a simple and inexpensivedevice whereby the singletree may have a slight forward movement beforethe vehicle is started, thus preventing sudden jars and shocks andrendering the strain upon the horse and harness more uniform.

Vhile I have described my invention as being especially applied tosingletrees, it is obvious that it may be used in connection withdoubletrees Without departing from the invention and with equally goodresults.

Having thus described my invention, what I claim is- The combination,with the singletree l, having the lugs 5 5 upon its upper and lowersides, and the flanged lugs 9 near each end, of the clip Il, embracingthe singletree and guided vby lugs 5 5, the spring S, the ends.

of the inner leaf of which Work in the lugs 9 and the outer leafprovided with a boss l0, the headed bolt 6, passing through the clip andboss, and the bar l1, carried by the clip for limiting its movement,substantially as described.

In testimony that I claim the foregoing as my oWnI have hereunto aiiixedmy signature in presence of two Witnesses.
